Description

Technical Field

[0001] The utility model belongs to the technical field of metal product processing, and particularly relates to a low-temperature boronizing equipment for steel pipe plugs. Background Technique

[0002] The low-temperature boronizing equipment for steel pipe plugs is an industrial equipment specially used for surface treatment of steel pipe plugs, aiming to improve the surface performance of steel pipe plugs through the low-temperature boronizing process. Boronizing is a chemical heat treatment process that can significantly improve the hardness, wear resistance and corrosion resistance of metal materials, especially in high-temperature and corrosive environments. Compared with traditional high-temperature boronizing, low-temperature boronizing is usually carried out at a lower temperature (about between 500°C and 600°C), which can reduce the deformation of workpieces, lower energy consumption, and shorten the treatment cycle.

[0003] The existing low-temperature boronizing equipment has poor sealing performance during low-temperature boronizing processing, resulting in easy air leakage during low-temperature boronizing processing, leading to a low hardness strengthening effect on the surface of the steel pipe. Therefore, it is necessary to perform secondary low-temperature boronizing processing on the steel pipe, reducing the working efficiency of the low-temperature boronizing equipment and causing waste of time and human resources. Content of the Utility Model

Therefore, it is necessary to perform secondary low-temperature boronizing processing on the steel pipe, reducing the working efficiency of the low-temperature boronizing equipment and causing waste of time and human resources.
